Companies have made impressive progress in measuring Earth’s environmental changes from space. GHGSAT, a emissions monitoring company in Montreal, Canada, tracked methane leakage from landfills and oil excavators. The PLANET photography company in San Francisco, California uses more than 200 satellites to record land and infrastructure for the energy, insurance and naval sectors. Data-Analytics, which continues in San Francisco, converts radio signals from navigation satellites into estimates of ocean height and wind speed to support weather forecast. European Airbus Airbus manages satellites that can be used to study volcanoes, wetlands and marine ice.
Space agencies, many of them, including the European Space Agency and NASA, notice the integration of commercial data in their governorates to make them available to researchers. Both clients have identified the externally produced data evaluation, providing science -based assessments for accuracy, geographical targeting and ease of use of notes.

As an academic researcher, I was excited to participate in efforts to increase the adoption of data from commercial satellites to complete the information provided to the public. For example, with the support of NASA, I started applying GHGSAT data to estimate methane emissions from the landfill site in Brazil. I also explore how to use data from companies such as Spire to support efforts to reduce the risk of hurricanes in Puerto Rico and Mexico.
I found that the data collected by commercial organizations is innovative and useful. But I also know that private companies alone cannot provide all the maintenance data that the world needs. They should not.
When governments discuss science budgets and consider the role of public and private sectors in environmental monitoring, it may be tempting to search for ways to increase efficiency and transfer public sector operations to the private sector. The progress made in commercial satellite operators may provide evidence that NASA will not need to run the largest number of satellites in the future as doing now. In fact, the request for US President Donald Trump’s budget for the fiscal year 2026 is proposed to cancel NASA’s funding for many of the government’s land governorate’s tasks. But this is the wrong lesson to learn from the progress of the private sector.
Instead, governments and researchers must continue to pursue a balance between the contributions of the trade and public sectors in environmental monitoring. Satellite -based land -based missions are still relevant, because they have many unique features.

First, these tasks are created to answer scientific questions or to maintain public services, such as weather forecast or flood response systems. Although commercial land retaining companies can contribute, government entities must take the initiative to ensure the production of data, models and predictions that are generally controlled and reliable.
